A Single-Dose, Randomized, Placebo- and Active-Control, Four-Way, Cross-Over Study for the Evaluation of the Effect of Tebipenem Pivoxil Hydrobromide (TBPM-PI-HBr) on the QT/QTc Intervals in Adult Healthy Subjects

Completed · Phase 1 · Has a placebo group

Conditions studied: TQT Study

In brief

This is a randomized, double-blind (with respect to Tebipenem pivoxil hydrobromide \[TBPM-PI-HBr\]/placebo only), placebo- and active-control, single-dose, 4-way crossover study that will enroll 24 healthy adult male and female subjects. There will be a washout period of at least 7 days between dosing in each period and each subject will receive all 4 treatments over 4 periods in a crossover study design.

• Medically healthy with no clinically significant medical history, physical examination, laboratory profiles, vital signs or ECGs, as deemed by the PI or designee.
• No clinically significant history or presence of ECG findings as judged by the PI or qualified designee at screening and prior to dosing of Period 1, including each criterion as listed below:
• Normal sinus rhythm (heart rate between 50 and 100 bpm, inclusive);
• QTcF interval (Fridericia's correction to the QT interval) ≤ 450 msec;
• QRS interval < 110 msec;
• PR interval < 220 msec.
• For a female of childbearing potential: either be sexually inactive (abstinent as a lifestyle) for 3 months prior to the first dosing and throughout the study or be using one of the following acceptable birth control methods:
• non-hormone releasing intrauterine device for at least 3 months prior to the first dosing and throughout the study.
• surgical sterilization of the partner (vasectomy for 4 months minimum prior to the first dosing. In addition, female subjects of childbearing potential will be advised to remain sexually inactive or to keep the same birth control method for at least 28 days following the last dose.
• For a female of non-childbearing potential: must have undergone one of the following sterilization procedures at least 6 months prior to the first dosing:
